To all whom it may concern:

Be it known thatI, JOHN FRANKLIN MAC- INnon, a citizen. of the United States, and a resident of the city and countyof Philadelphia, State of Pennsylvania, have invented certain new and useful "Improvements in Devices for Lubricating Eleyaton Guide- Rails, of which the following'isa specification.

My invention relates to improvements in devices for lubricating the guide-rail of elevators, and the object of my invention is to furnish a device for automatically applyin the lubricant to the rails as may be neede My lubricating device which is to be carried by the car, 111 any convenient and suitable manner, consists of a compression grease cup, or equivalent device, which is connected to a grease conduit which carries grease to one of the faces, preferably the front face, of the guide-rail. Connected to this conduit are conduits which carry the,

grease to the other faces of the guide-rail. The guide-rails of elevators are usually constructed with three guiding faces, a front face and two side faces, preferably my main conduit conducts the lubricant from the reservoir to the front face of the rail and from' the main conduit lead other conduits which conduct the lubricant to the other faces of the rail. Tn order that the lubricant he properly distributed and that there shall not be a waste it is essential that the grease distributers make and maintain a perfect contact with the faces of the guide-rail. If the rails were always in line and if'the guides of. the car had no play on the rails perfectly rigid distributors might be used, but in practice, and parti ularly after the car has been in use for some time, the faces of the rail are more or less out of alinemcnt and the guides of the car have more or less play, hence the lubricant distributers, which tributers, and my invention consists inthe a plan of my elevator guide lubricator, the grease cup being removed; Fig. 2, a front a section of Fig. 2 on line V V: Fig. 4, a,

elevation of the complete lubricator; Fig. 3,

sebtion of Fig. l on line Z--Z; Fig. 5, a section of 'Fig. 4 on line YY;'Fig. 6, a section of Fig. 3 online a 1 is a compression grease cup of my approved construction. 2, a conduit connected to cup 1. At its lower end the conduit 2 is connected with the distributor 3 which lubrica tes the front face of the guide-rail at. The dist-ributer 3, in order/that its face may at all times closely and flatly engageflthe front face of the guide-rail 4, of a piston like construction, that is it is free to move in and out of its bearing in the conduit 2, a stuffing box 5 of usual construction being employed to prevent the leakage of lubricant between the distributer and the con-' duit. A spring 6 forces the distributor outward and holds its working face against the front face of the guide rail 4. A feather 13, Fig. 6, prevents the part 3 from turning on its longitudinal axis. This movable arrangement insures a constant contact between the working face of the distributer and the front face of the guide rail when the conduit and connected parts, which are carried by the car, are, during the movemcpts of the car, moved to and from the ram The distributors .7 which lubricate the side faces of the guide rail 1 are furnished with a hollow stem 8 which is pivotally carried by the hollow arms 9 which are pivotally carried by the conduits 10 which are connected to the grease cup 1, preferably through the conduit 2, as shown. The arms 9 are, forced inward toward the guide-rail 4 by suitable springs 11, Figs. 1, 2 and 3. In the drawings the spring 11 is shown as. a flat spring one end of.which is held by the conduit 10 and the other end of which en distributers 7, may be moved inor out as may be necessary to compensate for irregularities in alinement of the guide-rails or for play of the car upon the rails. In con; nectlon with this arrangement the pivotal attachment of the grease distributers 7 to the arms 9 will insure the working faces of these distributers always flatly engaging the side faces of 'the guide-rail a condition essential not -only for the perfect lubrication of the rail but also to prevent .waste of grease. The grease being under pressure it will be seen that unless the contact between the distributers and the faces of the guiderail are maintained an unnecessary amount of grease will be used.

Fig. 4 shows a section through the pivotal connection of the arm 9 to stem8, the construction of the joint between the arm 9 and the conduit 10 being substantially the same. The stem is furnished with perforations 14 forthe passage of the lubricant I from one conduit to the other, the construction being substantially that of a plug cock.

Having thus described my invention I claim as new and desire to secure by Letters Patent:

In a device of the character described, in combination, a grease cup, a conduit con nected to said cup, an arm pivotally connected to said conduit, a notched segmentcarried by said arm, a spring carried by said conduit adapted to engage said segment to throw said arm inward, and a grease distributer pivotally carried by said arm, said arm and distributor forming a continuation of said conduit.
